Studio UI/UX iteration — studio-ux-10-native-capture¶

• Branch: cursor/studio-ui-ux-plan-loop
• Native: deploy/studio-demo/native/studio_viewport_capture.c + scripts/studio-ui-ux-capture-native.sh
• Harness: li-cursor-agents ux-harness/adapters/native_capture.py, target world-studio-native

Changes¶

• SDL2 viewport stub (grid, particles, selection HUD) captured under Xvfb when libsdl2-dev + xvfb-run present
• studio-ui-ux-capture-progress.sh calls native capture before HTML mocks; sets native_pixels from latest-native-capture.json
• studio-ui-ux-verify-native-capture.py gate (soft-skip without SDL)

Gap (this runner)¶

• libsdl2-dev not installed — native capture skipped; honest_native_viewport=false
